Lancaster, PA (April 2, 2009)--Linear Acoustic has started shipping the compact AERO.one DTV audio/loudness manager, with a special pricing offer through June 12, 2009.

Viewers are quick to notice loudness discrepancies between 5.1-channel network audio and local stereo programming and commercial insertions, and will voice their complaints--or simply switch to another channel. The Linear Acoustic AERO.one is said to address these issues by reformatting local stereo insertions to match the network's six-channel audio feed while also applying loudness and metadata control in order to maintain a consistent surround sound experience for viewers.

The UPMAX algorithm from Linear Acoustic operates in tandem with the company's new AutoMAX-II auto-detection algorithm to generate downmix-compatible 5.1 surround audio where appropriate. AutoMAX-II implementation in the AERO.one reportedly ensures that UPMAX processing is bypassed automatically and seamlessly when a 5.1 stream is detected, without switching artifacts or loss of dialogue. Switching may alternatively be controlled through GPI contact closures and the application of metadata.

To guard against loudness variations--the number-one viewer complaint--the AERO.one applies multiband, multistage processing to manage discrepancies between network and local programming and local commercial insertions. When an incoming 5.1 audio stream is automatically detected, loudness control processing is bypassed and only protection limiting is applied.

The 1RU AERO.one is said to be the first six-channel audio processor to be priced at under $10,000. Mindful of the tough economic climate, Linear Acoustic is currently offering a free upgrade to include HD-SDI de-embedding, reprocessing, and re-embedding capabilities plus redundant power supplies. The offer is open for orders placed through June 12, 2009, the federally mandated date for the analog broadcast switch-off.
